The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

A problem with this technique is that you have to make all the
parameters *NOPASS. There's a way to get around it: Create a second
prototype for the procedure with the same EXTPROC, but no parameters;
call it something like myproc_reset. Then when you want the procedure
to reset itself, call myproc_reset() instead of myproc(parms).
Personally I define all such "resetable" variables as global
variables. Most of my service programs have an "open" procedure
(which calls the "reset" procedure), a "reset" procedure, and a
"close" procedure.
I do use some static local variables, but only for purposes where the
caller doesn't have any say about them, or where the procedure
parameters inherently support whatever the caller needs to communicate
about them.
